YOU WOULDN'T wash greasy dishes or clothes in cold water and expect to get them clean. Why do you use a cold-water pressure washer to clean a greasy tractor? That's the question the salespeople at Hotsy cleaning equipment ask farmers. Although the company sells both hot- and cold-water pressure washers, it says hot water cleans twice as well as cold, and it sells more than twice as many hot-water models as cold-water ones. In total, Hotsy has 80 models of hot-water pressure washers.

The 555SS model, shown here, heats water to 180° before blasting it out in a 1,300-psi stream. As they say in the dish detergent commercials, grease doesn't stand a chance. Neither do corrosive fertilizers, chemicals, dirt, manure or weed seeds. The mobile washers use an oil-fired burner to deliver constant temperature using diesel fuel, kerosene or home-heating oil.

The 555SS uses a leakproof, 2-hp, 115v electric motor and comes with a 37-ft. power cord with safety ground fault interrupter. Price: $2,665. Contact Hotsy Equipment Co., Dept. FIN, 17 W. Peru St., Princeton, IL 61356, 800/553-5201, visit www.hotsy.com or www.freeproductinfo.net/fin, or circle 196.
